An earthquake of magnitude 2.9 occurred only 10 minutes ago 1 miles southeast of Mount Vernon, Washington, United States, the United States Geological Survey reported.
The quake hit at a very shallow depth of 4.1 miles beneath the epicenter near Mount Vernon, Skagit County, Washington, USA, early morning on Thursday, August 21st, 2025, at 1:01 am local time. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
A second report was later issued by The Incorporated Research Institutions for Seismology (IRIS), which listed it as a magnitude 3.0 earthquake. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 3.0.

Weak shaking might have been felt in Mount Vernon (pop. 34,100) located 1 miles from the epicenter.
